It is NOT a US caller- is a international SCAM ring. They are out of the country- and looking to scam you. Do not answer their call. BLOCK it and report them to the FCC. The FCC has a form online for these types of reports.Caller ID: 7452015421Caller: Unknown

Received a call from this number. Recording said to the effect "if you want to lower your card interest rate" without specifying what card they refer to. Pressed '9' to talk to someone a male voice came on and when I asked "who are you and why are you calling me" he hung up.Caller ID: 745-000-1234Caller: "Card Services"

Caller calls about every 30 minutes. The number cannot be blocked. It cannot be forwarded. I will not answer it as there is no identification regarding the caller, and there is no area code 745 in the USA on ATT or any service I've checked online. Tremendous nuisance. Harassment that's enough to make you crazy. It also is impossible to determine the identity of owners of this number by calling back the number, as the call goes to a recording which states that it is first necessary to dial a "1" or a "0" before making the call EVEN THOUGH I already DID dial a 1 before calling the number. Therefore it is entirely impossible to avoid harassment by the anonymous caller(s) at this number.Caller: identity not revealed

They kept calling and never left a voicemail. So one day as I was enjoying a couple pints of beer, they called and I answered. I asked who they were but they wouldn't give a response. Some kid just kept asking for my name.Caller ID: 754-555-5555
